LOOM SHUTTLE.

Application filed August 26, 1925.

The present invention relates to loom shuttles, and particularly to mechanically operated means for threading a shuttle.

An object of the invention is to produce manually operated means for delivering thread to an eye of a shuttle, or into such relation to the eye that it may be pulled therethrough.

Another object of the invention is to provide a thread moving member adapted-to extend into the eye of a shuttle for carrying the thread.

A still further object of the invention is to provide a device of this nature which is exceedingly simple in its construction, easy to manipulate, thoroughly reliable and efficient in its operation, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing 1- Figure l is a View in elevation of a shuttle embodying the features oi this invention,

Figure 2 is a fragmentary longitudinal section therethrough taken substantially on line 2-2 of Figure 3, and

Figure 3 is a fragmentary longitudinal lino 3---3 of section taken substantially on Figure 1.

Referring to the drawing in detail, it will be seen that 5 designates a shuttle, having the usual cavity 6 formed therein for reception of the thread package 7. A longitudinally extending groove 8 is formed on the side of the shuttle with the cavity 6, being disposed in extension thereof, and intersecting as is indicated at 9, an intermediate portion of the eye 10 which extends transversely through the shuttle. A pocket 11 is formed in the shuttle extending at right angles to the groove 8. An arm 12 Serial No. 52,603.

is pivoted as at 13 in the groove 11, and has one end movable through a slot 1-4; formed in the eye 10. This end of the arm 11 is provided with an angular thread engaging extension 15. A11 angular extension 16 is provided at the other end of the arm, and is engaged by a spring 17 holding the arm in the position shown in Figure 2 normally.

The thread from the spindle 7 may be led to extend through the groove 8 and held across the eye 10 by the fingers and then a finger may be engaged with the extension 16 to rock the arm 12 so that the extension 15 engages the thread and moves it to the position shown by the dotted line 19 in Figure 2, so that the thread may be engaged between the fingers and pulled through the eye.

It is thought that the construction, operation, and utility of the invention will now be clearly understood without a more detailed description thereof. It is apparent that changes in the details of description and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as 1' hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what I claim as new is:-

A. shuttle of tie class described including a body, an eye extending transversely of the body, said body provided with a longitudinally extending groove crossing and communicating with the interi'nediate portion of the eye, said eye provided with a slot, said body arovided with a groove extending from the slot, an arm pivoted at one end in the groove and having an extension at its other end movable in the eye, anexten sion at the first mentioned end oi the arm,

and a spring associated with the last mentioned extension for holding the arm nor mally inactive,

in testimony whereof I ailix my signa ture.
